Old 2019 model 3 SR+ upgrade

It work ! My 4 yrs old model 3 now can charge on a CCS adapter! This car is amazing! Thx A2Z for the upgrade before Tesla make it available. Happy to support a Qc company. Never stop exploring !

Works as promised

Great way to find the ECU for a self upgrade. Genuine Tesla part with less hassle.

Anthony Filipov
Working great

Everything works great

The CCS1 adapter and installation kit to get, best in the market!

I ordered the CCS1 install kit + the adapter for my 2019 Model 3. The install was straight forward, removed trunk trim to access the gen3 ECU, then disconnected the 12v battery, didn’t have to shut down the car, just turned the AC/heat off. Then swapped the ECU, connected with the special cable, then press n hold “Model 3”lettering on the screen to access the Service Mode, to reinstall the software and register the Electronic Control Unit. It took some time maybe 12 minutes for the software to finish, car rebooted, and was able to find the TM3 now has the CCS adapter support: Enabled. Doubled checked with j1772 level 2 charging great. Then went to my nearest Electrify America station and tested, 139 kW at a 150kW station with battery preconditioning turned on. The built quality is solid and light weight, the unit was not hot to touch after the DCFC session, a good sign. I felt lucky to chat with the A2Z CEO before I finalized my purchase. I’m so excited with this product and looking forward to the charging choices it will help to expand.
